Heikki Salmela

Chairman of the Board & Co-Founder

Heikki Salmela is the godfather of Gurulogic® Microsystems. He is a true entrepreneur who created Finland’s largest fast food chain Hesburger. He has a hunch for finding the just right people for each position, and his businesses continue to spread to new innovative areas. In 2001, Salmela decided to provide facilities for promising start-up companies. Tuomas Kärkkäinen approached him, inquiring about available office spaces. He was exactly what Salmela was looking for, and soon Gurulogic Microsystems saw daylight with a first task to develop a video surveillance system for the Hesburger chain. The success continues, thanks to the introduction of the industry leading GMVC® codec for universal data compression. In addition to Gurulogic® Microsystems, Salmela is involved in numerous innovative projects. For instance, he is the chairman of the board at a wastewater treatment technology company called Clewer.
